The IG recommended the Pentagon create a central quality management oversight office to help reduce delays and cost overruns.

The response last month from the Defense Department was they don’t need another layer of bureaucracy. “While we agree there are benefits to central leadership, it already exists,” Katrina McFarland, director of Defense Acquisition Resources and Analysis, said according to Government Executive. These quality checks “are in many cases are working poorly right now for a very simple reason: a shortage of trained and qualified acquisition professionals in the quality field.”

The IG requested another response, this time one that addresses its concerns, by December 5.
